#306 Microsoft.Net Framework when "Use Document Feeder (ADF)" is selected.

[Anthony Buttigieg]

I am running Windows 10 and using an Epson XP-850 MFP. I get the following error message when I select "Use Document Feeder (ADF)" in iCopy.

Microsoft.Net Framework

Dear Anthony,
this is a long-standing problem with some WIA scanners, one that is difficult to debug.
Please try with the attached version to see if the problem is solved. Please also attach the log file as instructed in the FAQ section of the website:

http://icopy.sourceforge.net/faq/

[Matteo Rossi]

In case the above doesn't work, please try with this one (Git Commit 6c660582). Thank you very much!

[Anthony Buttigieg]

Dear Matteo, thank you for this it's working fine now. I am attaching the log file but there's not much in it.

[Matteo Rossi]

Dear Anthony,

thank you for answering! With which attached version is the problem fixed? The first or the second? Could you please try also the other one and tell me if it works? I need as much information as possible on the problem to solve it once and for all.

Thanks
Matteo

[Anthony Buttigieg]

Dear Matteo,

You are very welcome. I tried the second one (Git Commit 6c660582). I will try the first one as well and let you know what happens.

Regards,
Anthony

Dear Matteo,

I have tried both versions and they both work with the ADF function. However if I enable duplex aquisition I get the Unhandled exception error again.

Regards,
Anthony

[Matteo Rossi]

Thank you for replying. So with duplex neither of the versions works? Which error do you get with the second version (Git Commit 6c660582)?

[Anthony Buttigieg]

Yes it does not work with either.

Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.

Dear Anthony, while I was trying to fix the duplex problem, I ran into this article of Microsoft knowledge base, which basically states that duplex is not supported in WIA Automation Layer (the API that I'm using). This means that, unless a particular workaround can be found for your MFP, I wont be able to find a general solution.
